Trending plants include hellebore, camellia, cacti, succulents and asparagus ferns.
The portable trend is for both indoor and outdoor plants, Squire's adds.
Playing on this trend, this autumn, Squire's is launching an exclusive range of indoor garden art and sculptural pieces combining cacti, orchids and succulents, arranged in frames for wall hanging, priced at £9.99 to £69.99.
Squire's deputy chairman Sarah Squire said: "As residential space shrinks, especially in densely populated urban areas, people are finding new and innovative ways to create impact in how they utilise outdoor and indoor spaces. It's a natural step on from the nation's obsession with baking, sewing and homecrafts."
The garden centre has also launched a range of ready-made planters called Planted by Squire's from £29.99.
