Gardeners' Notes:


On Nov 10, 2015, coriaceous from ROSLINDALE, MA wrote:

A pretty aromatic plant forming spreading woody-based mats which generally self-layer. The foliage is hairy and semi-evergreen here. It will tolerate limited foot traffic, which releases the scent. This is not a culinary thyme, and it does not make a good seasoning.

In my area (Boston Z6a), people wanting a uniform thyme lawn are usually disappointed, as plants can be short-lived, with much winter dieback, and usually the "lawn" grows in patches only. Here many weeds can outcompete it. It is not low-maintenance. It's better used in cracks and crevices about the edges of a path or in a rock garden.

Prefers lean, sharply draining soils.

There are many cultivars.

A slowly creeping, ground hugging mat of foliage with beautiful fuchsia colored blossoms in early summer. I'm not sure all of the plant files pics correctly depict 'Mother of Thyme' but instead another thyme. This plant doesn't grow more than 1-2" tall. It needs no care at all and even takes light foot traffic (at least by children). I planted two from 2x5" pots two years ago and both are now about 2' in diameter.

I grew some from seeds two or three months ago. They are growing well. I hope they thrive in Puerto Rico's tropical weather.

Does well in zone 9 tampa once established.march /april is a good time to start so it can be well established to endure summer heat/humidity that we have to deal with down here. stays evergreen here to 24 degrees that i know of(the lowest its been this year). clover can be a problem tough to get out once it gets in.
dont plant next to pavement/concrete in full sun the combination is just to much.full sun is ok as long as your not close to pavement/concrete. seems to like the cool winters turns darker green. most clumps grow from 12 to 24 inches max. ive had some flowering the first summer but nothing like the seed packets show mabey more this summer.?

This is an excellent lawn plant where grass fails to thrive due to poor, sandy soil and dry conditions. Here we get about 30" of precipitation a year, and summers can be dry. Mother-of-thyme does far better than grass in our lawn. It takes foot traffic well and smells like heaven. It mows beautifully and defeats weeds. It's easier to keep out of the garden beds than grass is, and if it does get into the beds, we dig it out and plug it into the lawn somewhere else. I highly recommend it.

Wonderful little plant for rock gardens, edging and just to use as "weed control" in some areas. Beautiful purple flowers in summer. Easily divided and/or moved. Takes root easily. I use it in a variety of places. Not finicky about soil as long as drainage is good.
