Frank is a low-growing bromeliad when in the ground, making tight showy clumps which lock out the weeds. Each plant matures about 18" diameter in a ground planting. It is important with clumping plants to use them in a location where they will be contained exactly in the bed they are wanted, and not become a runaway landscape nightmare. Likewise, in the original planting, spacing should consider the mature size of the plant, especially the diameter. Clumping bromeliad plantings will eventually require routine thinning- a good way to propagate plants for another bed if needed, or good stuff to give away and make friends.
This variegated bromeliad is another low grower in the ground, wider than 'Frank Maitland,' and a good way to brighten up shaded areas. This bed demonstrates a well-laid out, well-kempt planting which serves the purpose of covering the ground, but allowing space for each plant to expess its full shape.
