Dazzling vulgarities

Flowering in the garden now are the amazing and very rare white-flowered Dracunculus vulgaris. This wild and crazy aroid, which typically has a red/purple inflorescence, hails from the Mediterranean region, centered around Greece and Turkey. The late aroid guru Alan Galloway worked extensively to breed these, and since we now hold his collections, we wanted to share the wonder of his work. It is our hope that tissue culture will be able to make these amazing color forms available one day.

Ooops a Daisy

Many clonal plants we grow today are propagated by tissue culture…also known as micropropagation. In most cases, this involves taking tiny cuttings and growing them in a test tube filled with a goey algae product known as agar. Tissue culture allows many rare plants to be produced quickly and often inexpensively, which is great when it comes to making plants available far and wide. When vegatatively propagating plants through more conventional “macro” methods, it’s usually easy to notice when a mutation occurs. That’s not always the case in micropropagation since the plants are much smaller and don’t flower until they are grown out after leaving the lab. This is why daylily tissue culture has been disastrous. All kinds of floral mutation occur in the lab, only to be noticed years later after the plants are sold and grown out in home gardens.

All of the hellebores clones are micropropagated and so far, we have found almost no floral mutations…until this week. Below is a micropropagated double-flowered clone of the Christmas rose, Helleborus niger ‘Snow Frills’. The top image is the correct plant with two rows of petals. The bottom is a mutation we found in the garden in which the second row of petals is mutated. Honestly, we like the mutation better. As a plant producer, however, we don’t know what form we will receive in our next batch of plants from the lab, but that’s simply the nature of the process.
