Increase your Collection of Tall Bearded Iris

Last May I was fortunate to be able to spend the morning in Scotts Valley painting the tall bearded iris growing at Jim and Irene Cummins place. On their property they grow hundreds of varieties and if you are an aficionado of this regal flower you have a chance to add to your collection when the Monterey Bay Iris Society hosts their annual sale. Your first opportunity is at Deer Park in Aptos on August 4th from 9:00-noon and another sale takes place at Cabrillo Farmer?s Market on August 11th also from 9:00-noon.

Joe Ghio 2016 tall bearded iris hybrid

Jim and Irene welcomed my group of fellow artists sharing the history of their property and their growing tips. Amidst the beds of prized bearded iris is an impressive antique farming implement collection. This historic property dates back to 1849 when an older house was built as a stagecoach stop where a fresh team of horses could be changed out.

Jim told me that considering the history of the property he and Irene started displaying the old stuff they had and decided to add more by going to auctions and yard sales. Everywhere you look they have created an interesting vignette of plants and artifacts. Displayed on the old barn is an impressive vintage wrench collection as well as dozens of spigot handles. Antique tractor seats, watering cans, washing tubs, rusted bed frames, wagons, old kiddie cars- you name it, Jim and Irene have collected it.

Handmade birdhouses with vintage watering can collection

Due to the abundance of old wood on the property Jim said he started building Irene birdhouses. With so many interesting things to enjoy I had a hard time deciding what to paint. I took dozens of photos but settled on capturing their magnificent tall bearded iris in full bloom.

Jim is on the board of the Tall Bearded Iris Society (TBIS) and is also active in Historic Iris Preservation Society. As I walked around the blooming iris beds I noticed many had the name of Joe Ghio as their hybridizer. Some of the Cummins original rhizomes were collected from him as well as other iris gardens in the area. Early on they could only afford to buy a few of their older and less expensive offerings but as their garden began to grow they joined the Monterey Bay Iris Society.

The Cummins iris farm has been so successful that in 2019 when the National Convention is being hosted by Region 14 their garden will be one of the host gardens on the tour.

When I asked Jim for the growing tips that make his iris so spectacular he told me he mostly uses lawn trimmings and tree leaves along with their native sand to break the soil down. ?Iris don?t seem to care much as to soil type, they just need good drainage?, he said. He fertilizes with a balanced granular 15-15-15 fertilizer, using only an 1/8 cup or less sprinkled around each clump around Valentines Day and again in August or September. Another tip he told me was to be sure to plant the rhizomes real shallow with the tops showing and about 12-18 inches apart. They water every 2-3 weeks although he says they can go longer between irrigations.

At the upcoming sales, there will be a ?How to Grow Iris? handout available as well as many member of the society available to answer question. At $4 each for these spectacular iris or 20 for $60 adding to or starting an iris collection may just be in your future.

Growing Lavender

Lavender, a member of the mint family, is found across Europe, the Mediterranean, north and eastern Africa, southwest Asia to southeast India and fits right into our similar environment. Everybody has their favorite type. Mine happens to be a compact English variety called Hidcote but there are hundreds available including a new, tough, variegated one called ?Meerlo?. Here?s how to grow yours so it flourishes and doesn?t end up woody and spindly.

Lavender needs good?drainage. Incorporate organic matter if necessary to make the soil loose and friable. Compost is the best amendment because it is fertile and the uneven particle sizes create better air spaces and give the roots better anchors to attach themselves to. Check the soil’s?pH?(potential hydrogen) to make sure it falls somewhere between 6.5 and 7.5. If the soil is too acidic the lavender will not thrive. If the soil is too alkaline, the nutrients are ?tied? up in the soil and the plant cannot use them. Yellowed growth can be indicative of a soil that is out of balance. Adding compost can help to?balance the pH.

Mulching with a fine?mulch?or compost after planting?helps with the weed control. Avoid mulching right up to the stem of the small plant. Instead, leave a collar about two inches wide around the plant.

In the ground or in a pot, full?sun?is a must. In hot areas, some late afternoon shade can be tolerated without effecting flowering. Lavender in the field rarely needs?fertilizer, especially if compost is applied as a mulch.?More often, problems arise because the soil is not healthy. Avoid chemicals in pesticides, herbicides and fertilizers that kill or starve the beneficial organisms in the soil.

While Lavender is extremely drought resistant once established, they grows larger and produce more blooms with occasional deep watering depending on your soil type. This means that when the soil is?dry several inches down, water thoroughly, then let it dry before soaking again. Often I see older foliage that has yellowed due to lack of moisture.

Lavender plants should be pruned?every year immediately after bloom.?Pruning?should not be confused with harvesting. Pruning is necessary to extend the life of the plant. Cut back not only the flower stem, but also about a third of the gray-leaved stems as well. If the plant has been neglected, it can be cut back further, but avoid pruning back to only woody stems with no leaves showing. A plant pruned into the wood may push out latent (sleeping) buds or it may die.

It?s possible to have a lavender blooming in your garden most of the growing season. Here are my favorites.

Spanish lavender starts blooming early to mid spring. These do best with a good pruning about four or five weeks into the bloom cycle, which discourages these large bushes from becoming untidy and sometimes encourages a second sweep of blooms. Spanish lavender?is sometimes referred to as French lavender since it grows wild in France.

French lavender has the more traditional gray leaves but with serrated edges. This large, fast growing shrub is sometimes referred to as everblooming lavender.?French lavender?does best when kept at no more than three feet, including blooms. Goodwin Creek lavender is a hybrid of French Lavender with a shorter growth habit and a darker purple flower head that is held on a longer wand. It makes a nice border or edging plant.

English lavender (Lavandula angustifolias), like?Munstead and Hidcote start flowering in mid to late spring.?They look great when they flower,?and after pruning, remain a compact ball or hedge with exotically fragrant leaves the rest of the year. Hidcote is famous for its dark purple flower.

The English hybrids come in?third in the bloom cycle and continue into mid summer.?These are the workhorses of the lavenders. Provence?and?Grosso?are the best known and are the ones to line the drive or border the garden.

Ceanothus: The Most Valuable Plant in your Garden

Those of you who read my column regularly might have noticed I often write about plants that are valuable to the birds and the bees as well as butterflies and wildlife in the general. I have 10 bird feeders around my house. Four for the hummingbirds and the other six have black oil sunflower seed and hulled chips. At this time of year when there are so many young the extra food is much appreciated. I provide water and nectar plants for the bees and butterflies as well. If I had to choose one plant to grow that would provide the most benefit for all the critters it would be ceanothus. Hands down, it?s the best and here are some of my favorite varieties.

Ceanothus ‘Carmel Creeper’
Ceanothus ‘Heart’s Desire’

The groundcover varieties I have in my landscape are Anchor Bay, Carmel Creeper, Heart?s Desire, Centennial and Diamond Heights. If deer frequent your landscape you should stick with Anchor Bay, Heart?s Desire and Centennial but the others are great in protected areas.

One of the upright types I grow is ceanothus thysiflorus. It?s one of the earliest native shrubs to bloom in our area. Ceanothus thyrsiflorus grow along a narrow band close to the coast from Monterey to southern Oregon. I also grow Julia Phelps with those electric blue flowers and Ray Hartman.

A new variety I’ve recently learned about from my friend and fellow Press Banner columnist, Colly Gruczelak, is called Celestial Blue. She planted several 2 years ago from 4″ mail order sleeves and they are now 3 ft tall and 4 ft wide. In her sandy garden, home to her personal deer population, the flowers look like blueberry sherbet. With a light fragrance, described as grape tart, it makes a good screen or accent. This cultivar is probably a hybrid of Julia Phelps and Concha. A horticultural cultivar is simply a plant variety that’s been selected specifically for gardens. Celestial Blue flowers 9 months a year especially in the summer when it explodes with rich purplish blue flowers.

A great variety I often use when designing a garden is Ceanothus ?Concha? because it will accept summer water more forgivingly than most and tolerates clay soil more than other species.

Joyce Coulter ceanothus also tolerates clay, summer irrigation and shearing better than other cultivars. It?s a good bloomer, drought tolerant and is covered in spring with wildly fragrant blue three-inch flower spikes.

Ceanothus is often said to be short lived. Most varieties need good drainage, little summer water and don?t need soil amendments. In their wild conditions ceanothus plants have a natural life cycle of 10-15 years although some live longer.

Diamond Heights ceanothus

Several members of the ceanothus family can form a symbiotic relationship with soil micro-organisms and fungi, forming root nodules which fix nitrogen. This is a reason why fertilizing is not normally recommended. Adding fertilizer mights kill off the good micro-organisms. Ceanothus are better left fending for themselves.

Ceanothus provide excellent habitat for birds and insects. They are good for attracting bee and fly pollinators and are the larval host plants for the beautiful ceanothus silkmoth. Ceanothus seed is readily eaten by many local birds. Planting a ceanothus is an important step to attracting more birds and wildlife to your garden.

Early California Indians used the fresh or dried flowers of some varieties for washing, lathered into a soap. it has been said to relieve poison oak, eczema and rash.
