HA -- Hardy Annual.
Hardy annuals can stand some frost, so sow in the open ground well before the last spring frost date, or, in warm winter areas, sow in fall.
HHA -- Half-hardy Annual.
Half-hardy annuals will survive a very light frost but are planted in the open at the last spring frost date or a little later. They can also be started indoors 6-8 weeks before the last spring frost.
TA -- Tender Annuals.
Tender annuals are warm weather plants that cannot withstand any frost and prefer warm nights. Tender annuals with long weeks to bloom (16-18+) should be started indoors 8-10 weeks before the last spring frost.
I tried starting these indoors last spring but nothing germinated. Will try again in 2020 and update my review if I have success.
Hi Andrea, thanks so much for your feedback! I'm sorry to hear that you had trouble with germinating the tall verbena seeds. They can be irregular germinators and can take quite a while for germination. I'd be happy to send out a replacement seed packet for you to try again.
I’m having the same issue. It’s been 6 weeks and nothing is germinating.
We love these and plant clusters of them each year in random places. Zone 5B
