Rudbekia – Laciniata Seeds
We have grown this by accident and are the only grower; finally we have had it identified: a very hardy but somewhat forgotten perennial with very deeply cut foliage and a large very prominent raised central cone with small yellow petals. A giant for the back of the border growing 4/5 feet and very quick to form a sturdy clump, we do not need to stake them or support them in any way. From our original stock plant we have divided – however, when we sow from seed that has been sourced, we have noticed that although it is clearly listed as Laciniata, it is a slightly different plant. Our original plant seems to be unique in the extremely serrated leaf and vigour. This plant is one of our favourites as it seems to us to be so very special.
Sow indoors or in a greenhouse under glass, anytime between February and April. Sow onto moist seed compost and cover. They will need light and heat (70-75 degrees F) to germinate so please don’t keep them in the dark. Germination will take around 12-30 days, so be patient. As the seedlings begin to grow they should be individually potted on or thinned to around 30cm apart.
Rudbekia are all very tough and reliable, and they are invaluable for pollinating insects. The flowering season is continuous from Summer, all the way through until late autumn. Virtually bomb proof they are planted in most of the beds at Sonoma providing colour and structure. Rudbekia will form an expanding clump quickly and easily. They are tolerant of drought and do not need watering. We now grow 4 different varieties.
