A cute little perennial salvia named Marcus grows only a foot tall,
perfect for the front of the flower border. Considered a dwarf, it
blooms with masses of flower spikes filled with small,
violet-purple, two-lipped blossoms.
Caradonna, on the other hand, is much bigger, often growing to
30 inches tall. This variety of perennial salvia produces spikes of
dark purple blossoms.
Whether you're growing one of these popular new varieties from
Germany or any of the other perennial salvias, they all have
something in common. You can keep them blooming weeks longer if you
take the time to cut off old blossoms as they fade.
Another choice: instead of waiting for the flowers to fade, cut
the flower stalks when the blossoms first open. Salvias make
wonderful cut flowers for bouquets.
Sometimes salvias--particularly older plants that haven't been
dug and divided in a long time--fall open in the center as the
season progresses. By the time that happens, new shoots are usually
emerging at the base of the plant. If my plants fall open, I just
cut the old stems back to the ground. Soon the salvias look
springtime fresh again. Often they bloom again, although the
late-season flowers tend to be smaller than before.
Perennial salvias are workhorses in a sunny garden. They thrive
in the heat. They also easily survive drought (although they won't
look as lush or bloom as much without supplemental water). The
plants are also a great choice in gardens where deer regularly
dine. Thanks to the aromatic foliage, deer typically just pass on
by perennial salvias.
Blues and purples predominate in perennial salvias, but they
also come in other fun colors. Snow Hill blooms in white. Amethyst
is rose-violet.
If you like colorful foliage, there are perennial salvias that
can fill that bill, too. Burgundy Bliss has burgundy foliage, while
a variety called Purple Knockout has leaves of bronze, purple and
red.
There are many dozens of uncommon but wonderful species of
perennial salvia which, unfortunately, are not readily available as
plants. Luckily, salvias are easy to start from seed, which is
often much easier to find than plants. I got seed for one of my
favorites, Jurisici's sage (Salvia jurisicii), from the annual seed
exchange of the North American Rock Garden Society. This small
salvia grows about a foot tall with deep lilac blossoms and unusual
cutleaf foliage.
