Are Rudbeckia Annuals Or Perennials ?
Rudbeckia Hirta are usually grown as annuals in the UK and then popped in the Compost bin come Late autumn. But Rudbeckias can also be biennials or perennials depending on the variety you choose to grow. *The Rudbeckia genus comprises around 20 different species.
Rudbeckia is native to North America and was once regarded as a valuable medicinal aid by Native American tribes. The Native Americans would use the plant to wash and heal sores, swellings and snake bites.
Rudbeckia was introduced to Europe thanks to the action of one man, an American botanist named John Bartram (1699 – 1777). He sent Rudbeckia seeds to Europe via an Englishman named Peter Collins. Mr Collins then brought them to the attention of a swedish fellow named Carl Linnaeus….
Carl Linnaeus (1707 – 1778) was a Swedish botanist, zoologist, taxonomist, and physician and in 1753 he named the flower after his mentor and University teacher Olaf Rudbeck – like his mentor the flower was also tall in stature! The Hirta part was latin for rough and hairy! – If you’ve ever looked closely at a Rudbeckia flower you’ll understand why the name is so fitting!

How To Grow rudbeckia Hirta
- Sow Rudbeckia Hirta indoors from February to April.
- Sow in pots, modules or trays in a good quality compost at a depth of 1/2 cm
- Cover with a propogator lid or polythene bag and place on a warm windowsill
- Try to keep the soil damp but not wet
- Germination should occur within 14-21 days. Remove cover once seedlings emerge
- When Seedlings are large enough to handle, pot on into individual pots or modules.
- Plant out once all risk of frost has passed, 20-30cm apart in a full sun spot** Be sure to harden off indoor raised seedlings first
What Does Hardening Off Mean?
Plants raised indoors or in a greenhouse environment, need to be acclimatised to cooler temperatures and increased air movement for about two to three weeks before they are planted outdoors permanently. This is a ‘toughening up’ practice to prepare the plants for their new environment.
How to Harden Off
Place your plants out for a couple of hours in a shady part of the garden. The next day, leave them out again for two hours, but this time allow the plants an hour of direct sunshine in the morning. Gradually continue to increase the length of time the plants are in direct sunshine over the course of roughly two weeks.
Sow Direct Outdoors
- Direct sow Rudbeckia Hirta seeds outdoors where they are to grow from April to June
- Pick a full sun spot on well drained soil
- Rake to a fine tilth and sow seed seeds thinly, at a depth of 1/2 cm.
- Water regularly, especially during periods of drought.
- When seedlings are large enough to handle, thin them out to roughly 20- 30cm apart.

Rudbeckia Hirta Water Requirements
