Ajuga Catlins Giant
( Ajuga reptans ‘Catlins Giant’ )
Ajuga is one of my favorite perennial plants for the Northeast Florida garden. There are allot of different selections out there to choose from and the hardiness of them can vary greatly from one cultivar to the next.
I seem to be the type of gardener that once I decide I love a plant I just have to try every single one I run across! So I have field tested ALLOT of Ajuga plants here in the Northeast Florida landscape over the last 20 or so years.
Catlins Giant may be my all time favorite for the Jacksonville/ St. Augustine area. It just seems to hold up better to our rainy seasons.
Here is a few quick tips to make sure your new Catlins Giant Ajuga plants are as happy as they can be!
Preferred Exposure for Ajuga Catlins Giant:

To be even more accommodating, try finding a location that blocks the hot afternoon sun off the foliage. Direct morning sun is ok in irrigated gardens as long as something, whether it be a tree, a building, shed or even a trellis keeps the afternoon sun off the plant. Avoid locations that receive
afternoon sun or plant in a dappled shade location where nearby or overhead trees break up the hot sun
during the day.

water retention potting mixes. We are looking for excellent drainage for Ajuga plants so sandy soil with some good quality (light and airy) compost mixed in is ideal. I like to use the composted cotton from
– Salt tolerance unknown
Mature Size Variance:
– All Ajuga plants would fall under the groundcover category. Caitlins Giant may have big bold beautiful leaves but it still remains at a compact height most often around 6 inches or so in the garden. Expect Catlins giant to spread out to a width of 12-24 inches.
Blooms of the Catlins Giant Ajuga plant:
– Blooms during late spring are held just above the foliage and will blanket the
plant with bright purple – blue flower spikes. These plants are pretty enough to me when they are not in
bloom but quite stunning while blooming and don’t forget those blooms are butterfly attracting so that is an
