Article Says Don’t Mix Colors in a Pot of Lisianthus

Why not? If such a curious (ominous?) warning is made in the future, please include just a clue as to why, as this sort of thing can keep me wondering for months! Thanks.

Although some resources do mention this, they do not explain why...and most resources for growing Lisianthus flowers say they are fine mixed together, though in containers you may want to stick with the same type as far as height and such. In fact, the dwarf types would be ideal for pots.

Thank you for bringing this to our attention. Our editors have made appropriate changes to make this less confusing.

Lisianthus Plants

I received a basket of beautiful purple and lilac lisianthus plants for Mother’s Day, and I wonder, when they have finished, can I plant them out in the garden beds? If so, will they flower next year, or do I have to take seeds to grow afresh? If I have to take seeds, do they appear from flower heads and are they just bedding plants and not perennials?

Yes, you can plant them out in your garden once you are past all chance of frost.

Lisianthus are grown as a perennial in gardening zones 7-11, and as an annual everywhere else, since the winter will kill them in colder zones. Even in zones 7 and 8, the plant requires protection during the winter (being cut back and having straw placed over it), since it is sensitive to even mild winters.

Yes, it is possible to collect seeds from Lisianthus. This article explains how:

In colder areas, another possibility is to dig the plants up and keep them as houseplants during the winter.

LISIANTHUS

ARE THESE ANNUALS?

This depends on where you are located. In warmer climates that don't experience frost, they will be perennial. In cooler climates, depending on how cold it gets, they will either be annuals or biennials.
